Forged Carbon Material
I'm sure you could do it procedurally, but if you want to use an image texture you could go this way:


Unwrap your object with the Smart UV Project mode. Give it a black image texture.





Switch to Texture Paint mode, load a forged carbon image texture, choose Brush Mapping > Stencil (Cmd to move, CmdMaj to scale, CmdCtrl to rotate), paint the surface of your object, it will paint over your black image.





Mix your image texture with a Glossy node, play with the Glossy value and the Mix factor.





If the glossiness depends on the grey value, use the image as a factor in the Mix factor. I don't know forged carbon but you might also want to play with Clearcot, in that case use a Principled instead of a Diffuse.
